Letters Patent No. 97,439, dated November 30, 1869.

IMPROVED COMPOSITION FOR CLEANING MILLSI'ONES- T119 adi referred to inthese Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE M. Pn'rmnn, of thecity of Detroit, in the county of Wayne, and State of Michigan, haveinvented certain Improvements in the Composition of Matter for Cleaningand .Dressing Millstones, while in operation, of which the following isa specification.

The faces of millstones, as is well known, gradually wear away, andtheir channels become filled up, and

. grains of wheat. A greater or lesser quantity of the same ingredientsmay be used, but they should be taken in about the proportions abovegiven.

XVhen faces of the stone become smooth and have a glaze upon them, Iintroduce my composition through the eye of the stone while the same isin motion. It soon cleans off the face by removing the glaze, cleaningout the channels, and thus nieasurzv bly restoring the cutting-surfaces.

I. am aware that sugar or a similar substance has been introducedthroughthe eye of the stone for a' similar purpose, and also that compositionsof various washing compounds have been used; but these I do not claim.

first I do claim, is-

The composition made of the ingredients in the manner herein specified,and applied for dressing millstones, as set forth.
